Abstract

Segmented polyacetylene is formed by the introduction of sp3 defects through deuteration along the chains of ordinary trans-polyacetylene. A number of experimental data have recently been collected on segmented polyacetylene, (CHDy)x, containing concentrations (y) in deuterium atoms as high as 17%, or even about 30% [l-3].The experimental results have been previously interpreted in terms implying that the presence of sp3-bonded carbons has only a moderate influence on the conjugation of the polyacetylene π bands (due to hyperconjugation effects) [1–3].
